I had a telephone interview for the same role. They ask you about your experience in the field, general stuff about what projects you have worked on, what you got out of them. The interviewer I got was very friendly and actually made it a pleasure rather than a stressfull experience.The next stage is an assessment day.....not sure of the set up there. So if any have been to it, I would appreciate some pointers in terms of what they will look/test for.
